Here is Full Source Multiple UIPickerView in the TextField in Swift 3

class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {

@IBOutlet weak var textFiel1: UITextField!

@IBOutlet weak var textFiel_2: UITextField!   


 let piker1 = UIPickerView()
 let piker2 = UIPickerView()

let country = ["Ban","Ind","PK"]
let number = ["1","2","3"]


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    piker1.dataSource = self
    piker1.delegate = self

    piker2.dataSource = self
    piker2.delegate = self


    piker1.tag = 1
    piker2.tag = 2;



     textFiel1.inputView = piker1
      textFiel_2.inputView = piker2


}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return 1
}



func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {



    if pickerView == piker1 {
        return country.count

    } else if pickerView == piker2{
         return number.count
    }

    return 1
}

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {


    if pickerView == piker1 {
        return country[row]

    } else if pickerView == piker2{
         return number[row]
    }
    return ""
}

func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    if pickerView == piker1 {
        textFiel1.text = country[row]
          self.view.endEditing(false)
    } else if pickerView == piker2{
        textFiel_2.text = number[row]
          self.view.endEditing(false)
    }
}

}
